I would like to give special thanks to past president David Murdoch, who has served the Hazelnut industry over many years, driving development, in an advisory capacity, and as a nurseryman. Also David Null, “Nutt Ranch” Marlborough. David compiles the newsletter and adds some very interesting technical and management details each issue.
The new committee is made up completely of enthusiastic hazelnut growers.

HGA newsletter, winter 2003
In this issue our growers’ corner takes a look at the hazelnut operation at the Nutt Ranch in Blenheim, and we are listening to Bev and Dave Null.
This property was purchased in 1995 as 8ha of pasture land. The land was purchased with the growing of hazelnuts in mind. The land is marginal for horticulture use and is in a dry area of Marlborough.

Three factors must be considered in choosing pollinizer cultivars: 1) the amount of viable pollen produced, 2) compatibility, and 3) time of pollen shed.
The amount of viable pollen produced by a hazelnut tree is largely a function of the number of catkins on the tree and the viability of the pollen produced. Some cultivars set pollen in abundance Others typically set very few catkins. Some cultivars drop their catkins prior to pollen shed. Since one good Daviana catkin is estimated to produce 4 million pollen grains, the amount of pollen produced by a single pollinizer tree is tremendous.

Horticulturally speaking, the hazelnut tree is clearly out of the ordinary. It is more than just nutty. It is unique and wonderful. The way in which it achieves pollination in the winter and completion of nut set in the spring, is like no other horticultural crop that I have ever heard of. It is a “one of a kind”, just like some of the people in our industry!
Over the years, many researchers have investigated the growth and development of the hazelnut, in an attempt to unlock some of the secrets of this unusual plant. In fairly recent times, 1979, Dr. Maxine Thompson, of OSU, published a very informative article about the growth and development of the hazelnut flowers and nuts. It is one of those information-packed articles that is peppered with words like: megasporocytes, achesporial cells, funiculus of the anatropous ovule…you know what I mean, light reading.

HGA newsletter, summer 2003
Welcome to all members of the Hazelnut Growers Association. The setting up of an association takes a considerable amount of time and effort and I would like to thank all those who helped get the ball rolling. The transition from Southern Nut Growers Association has been reasonably smooth and their grant of $500 is appreciated. Likewise we are very grateful for the early support from the hazelnut action group to help with some of the setup costs.
